There’s two theories on the matter, what you are describing is the “abiogenesis” theory, which isn’t widely accepted right now.
There is some evidence that simple hydrocarbons form in the absence of any biological processes. Saturn’s moon Titan has never had any life on it, and it has a literal sea of methane. Tholins are another category of simple hydrocarbons that are found on several other dead moons where they couldn’t have originated from biomatter. However, we don’t actually have any real evidence that the kind of complex hydrocarbons we find in Earth’s deposits can form naturally without any biological matter as a “starter”. So the theory still has some hurdles to get over.

I would say you provided more than some. There’s massive, in-our-faces evidence.
Strong delusion finds its way past spiritual matters into simple facts of science and common sense.
